As an international tribute to August Aichhorn, many of his colleagues prepared this symposium. It represents a psychoanalytic study of the aspects of delinquency, beginning with its causes and general problems and proceeding through social psychology, penology and surveys. The book concludes with a bibliography of Dr. Aichhorn's writings, which are largely concerned with wayward youth. The work will be especially interesting to readers informed on psychoanalysis. The subject is still in an early investigational stage, and readers will find many differences of opinion and points of view.
